[0001] The present invention relates to the technical field of dairy product preparation, and in particular to a dairy product separation device and process. Background Art
[0002] The dairy product market has great potential and the industry competition is fierce. It covers multiple categories. At present, the rise of concentrated milk has driven the optimization and improvement of the relevant industrial structure. In the process of preparing concentrated milk, it is necessary to filter out the whey in liquid milk to enrich the milk protein in the liquid milk. Concentrated milk usually has a thick texture, is easy to absorb and has high nutritional value, and is deeply loved by consumers.
[0003] In the prior art, manual operation is required frequently. In a refrigerated environment, a pressing plate is used to manually squeeze to separate the solid residue and the emulsion in the dairy product. The operation is monotonous and consumes a large amount of manpower. At the same time, there is a lack of corresponding sensing equipment during the squeezing process, and the pressure on the dairy product cannot be sensed and guaranteed to be constant during the separation process, which may cause the filter bag to rupture and the quality of the concentrated milk finished product is not good. The whole production process is very inconvenient. Summary of the Invention
[0004] In order to improve the problems that occur in the separation process of dairy products in the above background art, the present invention provides a dairy product separation device and process.
[0005] The dairy product separation device and process provided by the present invention adopt the following technical solutions: A dairy product separation device includes a sealed tank and a pressing device arranged on the top of the sealed tank. A filter net tank is arranged inside the sealed tank, and a filter bag filled with dairy products is stacked in the filter net tank. The filter bag includes a metal filter net and an inner filter layer made of non-woven fiber material attached to the inner side of the metal filter net. A balance pressing plate is arranged at the top of the filter bag, and the edge of the balance pressing plate is clamped to the inner wall of the filter net tank. The output end of the pressing device abuts against the balance pressing plate and continuously applies pressure to separate the emulsion of the dairy product in the filter bag. The balance pressing plate includes an upper pressing plate and a lower pressing plate that are parallel to each other. A plurality of compression springs are evenly arranged between the upper pressing plate and the lower pressing plate, and the rebound distance is detected through the detection port of a distance sensor. The control port of the distance sensor is communicatively connected to the pressing device and controls the output of the pressing device.
[0006] Preferably, a central shaft rod is arranged inside the compression spring, and the bottom end of the central shaft rod abuts against the lower pressing plate. The central shaft rod passes through the upper pressing plate, and a check block is arranged at the top end of the central shaft rod.
[0007] Preferably, the pressing device includes a driving mechanism that outputs any one of mechanical pressure, air pressure, and hydraulic pressure. The output end of the driving mechanism is connected to a transmission member, and the transmission member passes through a through hole located in the middle of the top of the sealed tank and abuts against the balance pressing plate.
[0008] Preferably, a butting groove for butting the transmission member is provided at the middle position of the top surface of the upper pressing plate.
[0009] Preferably, the distance sensor uses an infrared distance sensor.
[0010] Preferably, a cooling pipe is coiled around the outside of the sealed tank, and the cooling pipe is externally connected to a circulating cooling device; a temperature sensor is arranged inside the sealed tank, and the temperature sensor is communicatively connected to a controller arranged outside the sealed tank and controls the refrigeration temperature of the circulating cooling device through the controller.
[0011] Preferably, the sealed tank includes a tank body and a top cover. The top cover is arranged at the top of the tank body and is in sealing cooperation with the tank body. A toothed groove is arranged in a staggered manner between the outer edge of the tank body and the inner edge of the top cover, and a sealing ring is arranged inside the top cover.
[0012] Preferably, the sealed tank is arranged inside a housing body, and universal wheels are arranged at the bottom of the housing body.
[0013] A dairy product separation process, applicable to a dairy product separation device, includes the following steps: Step 1: Fill the filter bag with dairy products, stack the filter bags in the filter net tank inside the sealed tank, and use the balance pressing plate to press the filter bags; Step 2: Seal the sealed tank, and the output end of the downward pressing device arranged at the top of the sealed tank butts against the balance pressing plate, so that the balance pressing plate is in a compressed and resilient state; Step 3: Detect the rebound distance through the distance sensor in the balance pressing plate. If it exceeds a certain distance, the downward pressing device outputs. The downward pressing device continuously applies pressure and keeps the pressure received by the filter bags in the filter net tank within a basic constant range. In a refrigeration environment, the emulsion in the dairy products in the filter bags is continuously discharged; Step 4: After the downward pressing device presses down to a certain limit, stop applying pressure and let it stand for 1-2 hours, and take out the separated dairy products in the filter net tank.
[0014] In summary, the present invention has the following beneficial technical effects: 1.

By outputting any one of mechanical pressure, air pressure, and hydraulic pressure through the downward pressing device, and cooperating with the distance sensor and controller on the balance pressing plate to control the output force, it is ensured that the pressure received by the dairy products in the filter net tank is basically kept constant. Without centrifugally destroying the milk protein structure, the solid residues and emulsion in the dairy products are separated more thoroughly.
[0015] 2. The filter bag adopts a double-layer structure. The inner filter layer separates the solid residues and emulsion of the dairy products. The metal filter net outside the inner filter layer enhances the structural strength of the filter bag, prevents the filter bag from bursting and yogurt overflowing due to the extrusion of the balance pressing plate, and ensures the product quality.
[0016] 3. The balance pressure plate uses a parallel upper pressure plate and a lower pressure plate, and is made in cooperation with multiple compression springs. The compression springs are positioned by passing through the axial center rods. The pressure at the output end of the lower pressing device is converted into the compression elastic force of the compression springs and the pressure of the overall lower pressure plate on the filter bag. The pressure is released to the top of the filter bag through the rebound of the compression springs. A distance sensor is added between the upper pressure plate and the lower pressure plate to detect the rebound distance. When the distance exceeds a certain value, the lower pressing device outputs, so as to keep the pressure on the filter bag in the filter net tank within a basically constant range, and then separate the emulsion of dairy products in the filter bag.
[0017] 4. The tank body of the sealed tank is hermetically fitted with the top cover, and a cooling pipe is coiled outside the sealed tank. The dairy products are kept in a sealed and cooled environment during the separation process, reducing the interference of the external environment and producing high-quality finished products.

[0020] The following Figures 1-5 will further describe the present invention in detail.
[0021] Embodiment 1 of the invention discloses a dairy product separation device and process.
[0022] Refer to Figure 1, Figure 2 , Figure 3 , Figure 4 , a dairy product separation device, comprising a sealed tank 1 and a pressing device 2 arranged on the top of the sealed tank 1. A filter net tank 3 is arranged inside the sealed tank 1, and filter bags 4 filled with dairy products are stacked inside the filter net tank 3. The filter bag 4 includes a metal filter net 32 and an inner filter layer 31 made of non-woven fiber material attached to the inner side of the metal filter net 32. A balance pressure plate 5 is arranged at the top of the filter bag 4, and the edge of the balance pressure plate 5 is clamped to the inner wall of the filter net tank 3; the pressing device 2 is arranged on the top of the sealed tank 1, and the output end of the pressing device 2 abuts against the balance pressure plate 5 and continuously applies pressure to separate the emulsion of the dairy product in the filter bag 4. The emulsion in the dairy product is discharged through the filter bag 4, and solid residues such as milk proteins in the dairy product accumulate in the filter bag 4.
[0023] Referring to Figure 5 , the filter bags 4 filled with dairy products are stacked inside the filter net tank 3. The filter bag 4 uses a whole filter bag 4 that conforms to the size of the filter net tank 3, or multiple small filter bags 4 are stacked. The inner filter layer 31 of the filter bag 4 is made of non-woven fiber material, and the membrane pore size is very small, which can effectively separate solid residues such as milk proteins in the dairy product from the emulsion of the dairy product. The penetration speed of the emulsion is relatively fast. Since the filter bag 4 is squeezed, the metal filter net 32 is attached to the outside of the inner filter layer 31. The metal filter net 32 uses a metal mesh structure to enhance the structural strength of the filter bag 4.
[0024] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the balance pressure plate 5 includes an upper pressure plate 6 and a lower pressure plate 7 that are parallel to each other. A plurality of compression springs 8 are evenly arranged between the upper pressure plate 6 and the lower pressure plate 7, and the rebound distance is detected through the detection port of the distance sensor 9. The detection port of the distance sensor 9 monitors the distance between the upper pressure plate 6 and the lower pressure plate 7 in real time. The control port of the distance sensor 9 is communicatively connected to the pressing device 2 and controls the output of the pressing device 2. The control port of the distance sensor 9 judges whether the rebound distance exceeds the set distance and then sends two kinds of electrical signals. The receiving end of the pressing device 2 receives the electrical signals and feeds back the output. When the distance between the upper pressure plate 6 and the lower pressure plate 7 exceeds the specified limit, the controller 11 controls the pressing device 2 to output pressurization. Compared with the problem that the pressure sensor may not be in full and uniform contact with the filter bag 4 when a pressure sensor is arranged at the bottom of the balance pressure plate 5, the distance sensor 9 arranged between the upper pressure plate 6 and the lower pressure plate 7 can more accurately sense the pressure information received by the whole filter bag 4.
[0025] Referring to Figure 1 , a liquid discharge pipe 11 for discharging the emulsion is arranged on the side wall of the bottom of the sealed tank 1, and a quick-release switch valve 26 is arranged at the liquid discharge pipe 11.
[0026] Referring to Figure 2 ,Figure 3 , Figure 4 , the upper pressing plate 6 and the lower pressing plate 7 are parallel to each other, and there is a certain distance between the upper pressing plate and the lower pressing plate, that is, the balance pressing plate has a certain thickness to ensure that the balance pressing plate presses downward horizontally as a whole, and the pressure received by the balance pressing plate from the output of the pressing device is stable. An axially centered rod 12 is provided inside the compression spring 8, and the bottom end of the axially centered rod 12 abuts against the lower pressing plate 7. The axially centered rod 12 passes through the upper pressing plate 6, and a check block 13 is provided at the top end of the axially centered rod 12. The balance pressing plate 5 converts the pressure at the output end of the pressing device 2 into the compression elastic force of the compression spring 8 and the pressure of the entire lower pressing plate 7 on the filter bag. The output end of the pressing device 7 applies pressure, the upper pressing plate 6 moves downward and compresses the compression spring 8. At this time, the length of the axially centered rod 12 passing through the upper pressing plate 6 increases, and the pressure is released to the top of the filter bag 4 through the rebound of the compression spring 8. The axially centered rod 12 returns to its original position, thereby separating the emulsion in the dairy product.
[0027] Refer to Figure 1 , Figure 2 , the pressing device 2 includes a driving mechanism 14 that outputs mechanical pressure. The driving mechanism 14 uses a differential motor. The output end of the differential motor is connected to a transmission member 15. The transmission member 15 uses a transmission screw. The output end of the differential motor is in transmission connection with the transmission screw and drives the transmission screw to screw in. The transmission screw passes through a through hole 16 located in the middle of the top of the sealed tank 1 and abuts against the balance pressing plate 5.
[0028] Refer to Figure 2 , Figure 4 , a butting groove 17 for butting against the transmission member 15 is provided at the middle position of the top surface of the upper pressing plate 6.
[0029] Refer to Figure 2 , Figure 4 , the distance sensor 9 uses an infrared distance sensor. The infrared distance sensor measures the distance based on the reflected infrared light. When in use, the infrared distance sensor is attached to the top of the lower pressing plate 7 or the bottom of the upper pressing plate 6. The reflected infrared light is received by the receiver of the infrared distance sensor to detect the distance between the lower pressing plate 7 and the upper pressing plate 6. The infrared distance sensor transmits the distance information between the upper pressing plate 6 and the lower pressing plate 7 to the receiving end of the pressing device 2 through the control port. The distance sensor 9 can also use an optical distance sensor.
[0030] Refer to Figure 1 , Figure 2 , a cooling pipe 18 is wound around the outside of the sealed tank 1. The cooling pipe 18 is externally connected to a circulating cooling device. The circulating cooling device uses a radiator 30 or a heat exchanger, as well as related supporting equipment. There is no need to build a cold storage and put the sealed tank 1 into the cold storage, reducing costs; a temperature sensor 19 is provided inside the sealed tank 1. The temperature sensor 19 is communicatively connected to a control panel 27 provided on the outside of the sealed tank 1 and controls the refrigeration temperature of the circulating cooling device through the control panel 27.
[0031] Refer to Figure 1 and Figure 2 , the sealed tank 1 includes a tank body 20 and a top cover 21. The top cover 21 is arranged on the top of the tank body 20 and is in sealing cooperation with the tank body 20. A toothed groove 22 is arranged in a staggered manner between the outer edge of the tank body 20 and the inner edge of the top cover 21. The top cover 21 is covered on the top of the tank body 20 and the top cover 21 is screwed. At this time, the toothed groove 22 between the outer edge of the tank body 20 and the inner edge of the top cover 21 changes from being staggered to being in the same position, realizing the sealing cooperation between the top cover 21 and the tank body 20. A sealing ring 23 is arranged on the inner side of the top cover 21 to increase the sealing performance.
[0032] Refer to Figure 3 , there are a large number of liquid discharge holes 28 on the side and bottom of the filter net tank 3. A handle is arranged on the top of the filter net tank 3, and a support frame 29 is arranged at the bottom of the filter net tank 3 to support it inside the sealed tank 1.
[0033] Refer to Figure 2 , the bottom edge of the sealed tank 1 is processed with a rounded corner. After the dairy products are separated in the filter net tank 3, the sealed tank 1 needs to be rinsed. The bottom edge of the sealed tank 1 is processed with a rounded corner, and a scraper is used to scrape off the residues on the inner wall of the sealed tank 1.
[0034] Refer to Figure 1 and Figure 2 , the sealed tank 1 is arranged inside the outer shell 24, and universal wheels 25 are arranged at the bottom of the outer shell 24 for easy movement.
[0035] Refer to Figure 1 and Figure 2 and Figure 4 , a dairy product separation process, applicable to a dairy product separation device, includes the following steps: Step 1: Fill the dairy products in the filter bag 4, stack the filter bags 4 in the filter net tank 3 inside the sealed tank 1, and use the balance pressure plate 5 to press the filter bag 4; Step 2: Seal the sealed tank 1, the output end of the pressing device 2 arranged on the top of the sealed tank 1 abuts against the balance pressure plate 5, so that the balance pressure plate 5 is in a compressed and resilient state; Step 3: Detect the resilient distance through the distance sensor 9 inside the balance pressure plate 5. If it exceeds a certain distance, the pressing device 2 outputs. The pressing device 2 continuously applies pressure and keeps the pressure on the filter bag 4 in the filter net tank 3 within a basic constant range. As the emulsion is discharged, the volume of the dairy products in the filter bag decreases. At this time, the pressing device outputs to maintain the pressure on the dairy products in the filter net tank. In a refrigerated environment, the emulsion of the dairy products in the filter bag 4 is continuously discharged; Step 4: After the pressing device 2 presses down to a certain limit, stop applying pressure and let it stand for 1 - 2 hours. Take out the separated dairy products in the filter net tank 3, rinse the sealed tank and the filter net tank, and perform the next processing.
